This paper proposes an automatic voltage regulator (AVR) based on series voltage compensation mechanism by AC chopper. The proposed AVR consists of a pulse-width-modulated (PWM) AC chopper and a transformer for series voltage compensation. The AC chopper circuit provides direct AC power without the need for an energy storage element, thus reducing the size and cost of the AVR. |
